The Enterobacteriaceae Isolated from Urinary Tract Infections in Kerbala City

Abstract

Objective: The goal of this study to determine the most common
microorganism that causes urinary tract infection (UTI) in Kerbala city/
Iraq, and study of susceptibility of this causative agents against some
antibiotics which used as treatments.
Methods: Sixty specimens were collected from urinary tract infections in
Kerbala city/ Iraq from September to December 2016. The bacterial isolates
were identified tested for antibiotics sensitivity test. Resistance breakpoints
used were those published by Clinical and Laboratory Standards Institute
(CLSI), including: Nalidxic Acid (resistance ? 13 mm), Trimethoprim
(resistance ? 10 mm), Norfoxacin (resistance ? 12mm), Ciprofloxacin
(resistance?15mm)and Trimethoprim/sulfamethoxazole(resistance?10mm).
Results: The most common organisms of UTI infection were Escherichia
coli (48%), Citrobacter spp (22%), Proteus spp(12%), Klebsiella spp(8%),
Pseudomonas spp(6%), Moragenella spp(2%) and Providencia spp(2%).
Among all 50 isolates , 48% were resistance to Nalidxic Acid , 40% to
Trimethoprim and 28% to Norfloxacinas. For the 24 Escherichia coli
isolates, resistance rate were: Nalidxic Acid (50.0%) ,Trimethoprim (37.5
%), Norfloxacin (33.33%), Ciprofloxacin (16.67%) and Sulphamethoxaole/
Trimethoprim (58.33% ).
Conclusion: From the results carried out in this study, it’s concluded that
E.coli isolates responsible for UTI infections and the higher rates of
antibiotics resistance to Sulphamethoxaole/ Trimethoprim.
